Oran Pre-Cast’s portal frame system uses column, roof beam and gutter elements to provide clear spans of up to 36m in width.

Intermediate level beams can easily be included, to allow for office or split level storage solutions. The external columns and roof beams are supplied with bolts to allow for the quick follow on installation of lightweight steel cladding.

The lateral stability of the frame is typically provided by a combination of the external or internal walls, and the diaphragm action of the roof structure.
